摘　　要：蒸汽压力对再热机组空负荷稳定性有很大影响,在额定主蒸汽压力下,若再热压力高于其额定值的60%,机组将不能维持空转,本文从运行和设计角度提出了两种解决办法。Steam pressure exerts a significant effect on the stability of reheat steam turbine governing system under zero-load conditions. Under a rated main steam pressure, if the reheat steam pressure is higher than the rated value by 60%, the turbine governing system will be unable to sustain a stable operation. This paper proposes two methods for dealing with this problem from the dcsign and operat ion viewpoints.
